.T0 all whom it" muy concern;

Beit known that I, JOHN F. SCHENCK,a citizen of the United States, residing at Lawndale, in the county of Cleveland and State of North Carolina, have invented new and use- .ful Improvements in Thread-Winding Machines, of which the following is a specifica- My invention relates to a thread-winding machine of the type in which thread is Wound upon a cop-tube in recrossing spirals running alternately inopposite directions upon and from endto end of the cop-tube, which latter is carried by a winding-spindle. In Letters Patent No. 638,360, granted to me December, 1899, a machine of this character is shown in which an oscillatory threadguide carrier is mounted concentric with the axis of the shaft which carries the cam for reciprocating the thread-guides. In Patent No. 652,646, granted to me June 26, 1900, a machine of this character is shown in which the thread-guide carrier is immovable during the winding operation and the frame which carries the rotary winding-spindle recedes in a horizontal path from the threadguide as the cop increases in size.

The machine formingthe subject-matter of the present application diii'ers in principle from my two patented machines in that in the former I provide a construction in which the thread-guide carrier moves in a horizontal path from the winding-spindle as the cop increasesin size. The principle ofthe operation involved in having the thread-guide carrier recede from the spindle in a` horizontal path is substantially the same as in having the spindle recede from the thread-guide carrier in the saine manner. The advantages derived from the latter mode ot' operation are 'of said Patent No. 652,646 may be dispensed with, thus adding to the simplicity of the machine, the spindles may be placed closer together and extend at right angles to the length of the machine, so that the ends point toward the operator, in which position they may be moreconveniently attended to, and inally the parts are so arranged that while both the thread-carrier and the thread-guide recede from the spindle only the latter is reciprocated by the cam to properly lay thread upon the tube or cone, thus insuring a light or easy motion to the machine.

In the present invention I also show an eX- tremely simple means for changing from a ,tube Wind to a cone wind, and vice versa. In other machines of this character the use of dierent gears for this purpose is necessitated or the thread-carrier frame must be set out of parallel with the cam-shaft, thus throwing the sides of the roller which runs in the cam-groove slightly out of parallel with the sides of the said groove, thereby causing the machine to run less easily and smoothly, and the greater the taper or incline of the cone-shell the greater would be the difficulty of doing good work. In the present machine no matter how great the incline of the spindle to the thread-carrier frame both the thread-carrier and spindle run just as true and as well as when winding tubes.

In order that my present invention may be fully understood, I have illustrated the saine in the accompanying drawings, in which- Figure lis a front elevation of the machine, a part of the frame being shown in section.

Fig. l] is a detached View in elevation show- ICO ing a modified form of differential gearing, and Fig. 12 is a sectional detail view of a portion of the clutch mechanism.

To enable those skilled in the art to which my invention relates to make and use the same, I will now-describe said linvention in detail, referring to the drawings, wherein the numerall indicates the spindle, which is journaled in bearings 2 3 on a spindle-frame 4. Said spindle has a fixed collar 5, located at the outer side of the bearing 2, and set-co1- lars 6 7, located, respectively, on opposite sides of the bearing 3, which arrangement permits the insertion and securing of the spindlein place in and its ready removal from the bearings 2 3, as will be understood. A bevel-gear 8, having a hub 9, is also removably secured on said spindle adjacent to the bearing 2 by means of a set-screw 10. The spindle-frame 4, as shown more clearlyin Fig. 4, may be cast as an integral structure and comprises'a dat base 11, from opposite ends of which extend upward projections, affording at their outer ends the bearings 2 3. About midway between the ends of the base, and at one side thereof, is a lateral extension 12, having a curved elongated slot 13. (See Figs. 3 and 5.) A circular aperture 14 is provided centrally of said base, and the slot 13 is struck 'on an arc concentric with the center of said aperture. The spindle-frame 4 rests upon the upper side of a flat frame member 15, extending transversely of the machine, and is centered thereon by means of a vertical shaft 16, which passes through an opening in the frame member 15 and through the aperture 14 in the base of the spindle-frame. The spindle-frame is free to revolve about said shaftrand may be set and held at any desired angle with reference to the thread-carrier frame through the medium of the curved slot 13 and a set-screw 17 passing through said slot and having a screw-threaded engagement with the frame member 15. On the upper end of the shaft 16 is removably .secured a bevel-gear 18, similar in all respects to the gear-wheel 8, with which it is in mesh.

19 indicates an upper bearing for the shaft 16, which bearing is secured, as shown, to the under side of the frame member 15. A

, set-collar 20 is secured on the shaft 16 immediately beneath the bearing 19 to limit the upward movement of said shaft. 21 indicatesa lower bearing for said shaft 16, which bearing is secured to the upper side of a frame member 22, located beneath and extending parallel with the frame member l5. A set-collar 23 is secured on the shaft 16 immediately above the bearing 21 to limit the downward movement of the shaft. On the lower end of the shaft 16 is removably secured a bevel-gear 24, which is adapted to mesh with a large bevel-gear 25.

The drive-shaft 26 is supported in bearings 27, suitably secured to depending portions 28 of the frame of the machine. The shaft 26 extends parallel with the length of the machine and is driven, by means of the beltpulley 28, from any suitable source of power. (Not shown.)

The thread-guide carrier is indicated by 29 and comprises an upper part 30 and an under part 31, the two parts being separated from each other to provide a longitudinal space or slot 32 by meanslof washers 33, located at 0pposite ends of said parts. are secured together at opposite ends by means of the screws 34. The lower part 31 of the thread-guide carrier is provided with a vertically-disposed groove 35, which in connection with the horizontally-disposed groove 32 between the two parts of the thread-guide carrier forms a guide for the thread-guide, as explained later on. As shown in Fig. 9, the upper part 30 of the thread-guide carrier is provided for a part of its length corresponding to the extent of travel of the thread-guide with a lateral extension 36, extending upward at right angles from which is a flange 37, against which the rear side of the upright part 38 of the thread-guide is adapted t0 bear,

as shown more clearly in Fig. 8. The under part 3l 0f the thread-guide carrier is in the form of the letter L, the foot ofwhich constitutes a downward-depending flange 39, in which is formed the groove 35. The {iange 39 has centrally of its length a downward extension 40, the purpose of which will presently appear. The thread-guide as a whole is shown in detail in Fig. 10 and comprsesa rectangular bar 41, extending at right angles from which at its upper side is a short arm 42, located at the extreme end of the bar. Extending upward at right angles from the end of the arm 42 isthe short projection or finger 38, constituting the thread-guide proper, and having its'upper side rounded and provided with a slot 43 for receiving the thread. Near its opposite end the bar 41 is provided with a lug 44, extending at right angles from its upper edge, while at its extreme outer end said bar has an upwardly-extending projection 45, on the inner side of which is a stud 46, carrying a friction-roller 47. As shown in Fig. 8, when the thread-guide is in position in the guide-carrier the bar 41 will seat edgewise in the groove 35, while the arm 42 extends entirely through the slot 32, so that its projection 38 extends upward parallel and in contact with the rear side of the flange 37. The lug 44 is adapted to slide in the slot 32 as the thread-guide reciprocates. The arrangement described provides for an even or steady movement of the thread-guide, as will be apparent without further specification. The thread-guide is reciprocated by means of an ordinary heart-cam 48, the cam-groove of which is indicated by the numeral 49. The upper edge of the thread-guide carrier is level with the center of the spindle, and the grooves in the same stand at right angles to the length of the machine all the time. The movement of the thread-guide is therefore always in a horizontal plane and at right angles to The parts 30 3l IIO the cam shaft 61, which is parallel with the drive-shaft 26 and Wit-h the length of the machine. The thread -guide carrier, With its thread guide, is adapted to recede from the spindle as the cop increases in size and is held in a horizontal position by the means now to be described. 1

The numeral 50 indicates a rod extending parallel with the drive-shaft 26 and suitably secured, as by a set-screw 51, in an upright casting 52 of the frame.

53 indicates a fiat. metal plate, cast integral With and extending at right angles to which is a relatively long cylindrical sleeve 54,which is slida-bly mounted upon the rod 50. Cast integral with the plate 53 and extending downward therefrom is au arm 55, the lower end of which is provided With a rectangular recess 56, adapted to tit snugly over and slide on a rib 57, formed ou the upper side of a plate 5S, secured to the frame of the machine. The projection 40 of the thread-guide carrier is provided With an aperture 59,through which the sleeve 54 extends, and said projection is secured, by means of screws 60, to the plate 53.

It will be seen that the thread guide carrier, the plate 53, sleeve 54, and arm 55 will all move together as a single mechanism. The rod 50 insures the movement of these parts in a straight horizontal line, While the engagement of the arm 55 with the guide-rib 57 prevents rotation of the sleeve 54, and consequently of the thread-guide carrier also, upon the rod 50. The guide-rib 57 is long enough to permit the maximum outward movement of the thread-guide carrier, as Will be understood.

The cam 48 is mounted upon the cam-shaft 61 in such manner as to be capable of sliding thereon, and to this end it is provided with a hub 61, which is mounted upon and rigidly secured to a relatively long sleeve 62, having akeyway extendingthroughoutits length and corresponding to a similar keyway formed in the camshaft, into which keyways akey 63 is inserted to prevent rotation of the sleeve relative to the cam shaft. At the same time the sleeve is mounted loosely'u pon its shaft 61, so as not to bind thereon and to be oa pable of sliding thereon, as previously stated. The hub 61J projects slightly beyond each side of the cam 48 and affords two shoulders 64 and 65. The outer side of the thread guide carrier normally bears against the face of shoulder 64, and as the cop builds up and forces the thread-guide carrier outward the cam 4S will also be forced outward, so that the roller 47 on the thread-guide Will maintain its proper position in the. cain-groove 49. Ot' course the pressure of this roller against the bottom of the camgroove will also have the effect of making cam 48 recede uniformly with the thread -guide carrier as the copA increases in size.

The numeral 66 indicates an arm having a hub 67 mounted on the sleeve 54 and held in place by a set-screw 68. The outer end of the arm4 66 rests against the face of the shoulder 65, and the purpose of this arm is to cause the return of the cam 48 as the thread-guide carrier is moved toward the spindle to begin the winding of another cop. The groove 49 in this cam is so cut that when the cam is revolving at a regular or uniform speed the speed of movement of the thread-carrier is the same in every position of the cam, and the return traverse thereof at the end of its movement in either direction is inst-antaneous. The bearings of the cam-shaft are indicated at 69.

At this point it may be Well to state that, as in the case of my other machines described in the patents named, I mayemploy any given number of winding-spindles, it being onlyv necessary to make the shafts 26 and 61 and the rod 50 of a length necessary to accommodate duplicate sets of the mechanism thus far described.

In adjusting the spindle for cone-winding it will be understood that as the spindle is turned to the proper angle relative to the thread-guide carrier, as shown in Fig. 5, the engagement of the spindle with the thread guide will simply cause the thread-guide carrier and sleeve 54 to be moved back the requisite distance on the rod 50.

As the cam 48 revolves rapidly, it is desirable to balance the same, so that it Willrun smoothly or Without jerking. To this cud I provide an extension 70 on the butt-end of the cam and place thereon a sliding Weight 71, which may be held in any adjusted position on the extension 70 by means of a setscrew 72.

For holding the tubes upon the spindle 1 in Winding cylindrical cops I prefer to use the device shown in Fig. 7 of my Patent No. 638,360, before mentioned. For winding conoi'dal cops, as shown in Fig. 5, I will use the holding device forming the subject-matter of Patent No. 676,335, dated June 11,1901, and assigned to me by the patentee,William E. Moffatt. Other means torholdiug either the tubes or cone-shells on the spindle may be used, if preferred, and as such devices do not form a part of the present invention I have deemed a reference to the preferred forms of holding devices sufficient Without further description or illustration.

As before stated, by extending the shafts 26 and 61' and t-he rod 50 I can duplicate the mechanism described any number of times and provide each machine with a pluralityof Winding-spindles. When this is done, it is desirable to provide means for starting and stopping any one of the spindles Without affecting the rotation of the others; To this end I provide the mechanism shown in Figs. 1 and 12 and which will now be described.

Slidably mounted upon the shaft 26 is a sleeve 73, Which lies between a fixed collar 74 and a friction-disk 75, secured to the outer face of the bevelgear 25. Said bevel-'gear is loosely mounted upon a sleeved extension of IOO IIO

rgb

the bearing 27. The sleeve 73 is provided with a conoidal or tapered portion 76 to act upon the extremities v77 of bent or curved arms 78, which are pivoted intermediate their extremities, as at 79, to` radial arms 80, rigidly connected with the shaft. The ends of the arms 78 opposite the extremities 77 are pivoted, as at 81, to clutch-shoes 82, having a flat bearing-face adapted to engage the surface of the friction-disk 75. The extremities 77 of the arms 78 are preferably in the form of adjustable screws to facilitate the adjustment necessary to secure correct action of the friction-clutch. The radial arms 80 are rigidly connected with the shaft through the medium of a hub 83, having an angular portion 84 to enter a similarly-shaped socket 85 in the inner end of the sleeve 73 when the latter is shifted toward the radial arms 80, which is effected through the medium of a clutch-lever 86, pivoted, as at 87, to a framepiece 88. The screw extremities 77 enter longitudinal grooves 89, arranged diametrically opposite each other in the sleeve 73. The clutch-lever 86 suitably engages an annular groove 90 in one end of the sleeve 73, the construction being such that the sleeve can turn independent of the clutch-lever and is moved longitudinally in one or the other direction by swinging the latter. The sleeve is also constructed with two arms 91, extending from the socket part 85 and having lugs 92 to cooperate with a spring-pin 93projecting from the outer side of the friction-disk 75 when the sleeve is moved a sufficient distance to place the lugs 92 in the path of said pin, with which one or the other of said lugs will engage. When the parts are in the position shown in Fig. 1, both clutches are out of action, and if now the clutch-lever 86 is gradually moved to the left or toward the gear 25 the sleeve 73 will be correspondingly moved, and the conoidal part 76 thereof will gradually force the screw extremities 77 radially outward, thereby turning the arms 78 on their pivots 79 and causing the clutch-shoes 82 to gradually act upon the clutch-disk 75, and since the sleeve 73 and hub 83 are constantly rotated the disk 75 and gear-wheel 25 will be thereby rotated, imparting through the gearing described rotation to the spindle 1. The clutch-disk can slip in contact with the clutchshoes, and since these parts constitute a friction-clutch it is possible to very gradually start the spindle, which is desirable, especially where the spindle is started when the winding of the cop is nearing completion, and the diameter of the same is such that its surface speed would be comparatively swift and render the thread liable to be broken by the sudden pull thereon. In other words, the take-up of the spindle when the cop-tube on the same is wound nearly full is ordinarily so rapid that if the spindle is at this time started it will suddenly jerk the thread, and perhaps break the same, before the bobbin or Vswift carrying the thread to be wound into a cop commences to turn. By the employment of the friction -clutch above described the spindle is slowly started, thereby starting the bobbin or swift before the positive clutch composed of the lugs 92 and spring-pin 93 is thrown into action. The positive clutchis desirable for the purpose of positively rotating the spindle and maintaining it at the high speed desired in a cord or thread winding machine. A

To maintain the positive clutch in action after the clutch parts or sections 92 93 are engaged by the movement of the clutch-lever 86 the required extent to the left and to hold the same out of action when the said lever has been moved to the position shown in Fig. 1, I pivotally connect to the clutch-lever 86 a rod 94, having a shoulder 95 near its outer end adapted to engage with a lug 96 through the medium of a spring 97 when the lever 86 has been moved to the left= as described. The said spring and lug are located on an upright 98 of the frame. 'Located on said upright is also a hanger 99, which supports the rod 94, and between said hanger and a fixed collar 100 on said rod is a coiled spring 101, which operates to return the clutch-lever to the position shown in Fig. 1 when the shoulder 95 has been moved out of engagement with the lug 96. The device just described, however, is more or less conventional, and in lieu thereof any preferred means may be employed-such, for instance, as that shown in Fig. 6 of my said Patent No. 638,360. In this patent I have also shown a clutch mechanism similar to that described herein, except that in the patented construction I employ iixed lugs 32 on the friction-disk 12 to engage the lugs 31 on the sliding sleeve. An objection to this latter construction, however, is that the iixe'd lugs might come together end to end, and thus prevent the conical sleeve and disk from coming together and the hand-lever 25 from being shifted to the left as far as it should go. This objection is obviated in the present instance by the use or the spring-pin 93 on the friction-disk 75 in lieu of a fixed lug, so that if the lug 92 should strike against the end of the pin 93 said pin will yield and permit the sleeve to be moved the requisite distance to the left. Where a one-spindle machine is used,-I would dispense with the clutch mechanism just described and mount the bevel -gear 25 fast on the shaft 26, as shown in Fig. 6.

In order to hold the thread-guide in yielding contact with the oop being wound, I secure on the upright 52 of the frame an arm 102, on which is mounted agrooved roller 103. Over this roller runs a cord 104, secured at one end to the arm 55 and at its opposite end carrying means for supporting a weight or weights I have shown herein two different arrangements for varying the speed of the cam-shaft, that shown at the. right of Fig. l comprising a differential or epicycle train of gearing hav- ICO IIO

ing interchangeable gears of varying diameter or size and being the same arrangement shown and described in my said Patent No. 638,360. inasmuch, however, as the relative positions of the cam-shaft and drive-shaft are reversed in the present case, a brief description of this differential gearing as applied to the present apparatus will be given.

The drive-shaft 26 is provided with an attached gear-wheel 106, meshing into a similar gear-Wheel 107, loosely mounted on the cam-shaft 61 and rigidly connected to or formed integral at one side with a bevel-gear 108, meshing into two oppositely-arranged bevel-gears 109 and 110 of the same size, which in turn mesh into a bevel-gear 111 of the same diameter as the bevel-gear 108 and rigidly secured to the cam-shaft 6l. lllhe journal-bearings for the bevel-gears 109 and 110 are provided on a stud or bracket 112, bolted or otherwise rigidly secured to the web of a comparatively larger differential gear 113, suitably constructed for the passage therethrough of the smaller bevel-gears 109 and 110 in such manner that these gears properly mesh into the bevel-gears 108 and 111, located at opposite sides of the differential gear. The dilfereutial gear meshes into the pinion 114, formed integral with or rigidly secured to a bevel-gear 115, mounted on a short shaft 116 and engaging the bevel-gear 117 on the upper end of a perpendicular worm gear or Wheel shaft 118, carrying at its lower end 'one of the interchangeable worm gears or Wheels 119. A number of such wheels 119 of dierent sizes are provided, and whichever one is mounted upon the worm-shaft 118 operatively engages aworm 120, rigidly secured to the drive-shaft 26. The worm-wheel shaft 118 is mounted in suitable bearings on a vertical supporting frame or plate 121,which is susceptible of adjustment relatively to the driveshaft to enable the interchangeable gears to Vbe employed and to properly engage with the worm 120. The frame or support of the wormwheel shaft may be adjusted through the medium of any suitable devices; but, as here shown, the frame or support is mounted at its upper end on the short shaft 116 and is provided at its lower end with a slotted arm 122, through which passes a bolt 123, by which the frame may be adjusted, as will be obvious. The interchangeable worm-wheels serve to rotate the differential gear 113 at varying speeds, and through the medium of the differential or epicycle train above set forth the speed of rotation of the cam-shaft may be varied to suit the conditions required Where fine or coarse thread is to be Wound into cops.

This machine is what is known as a closewind machine. In orderto produce the work referred to, a proper relation between the speed of the spindle and the thread-carrier must be maintained. The spindle must make either a certain number of revolutions and a small fraction over or must lack said small fraction of making a certain number of revolutions to each traverse of the thread-carrier, and the small fraction of a revolution referred to must be greater for coarse thread and less for fine thread. The size of this fraction of a revolution is regulatedby the speed of the differential gear 113 and whether the spindle maires a fraction over a given number of revolutions to one traverse of the threadcarrier or a fraction under depends upon the direction in which the diiferential gear 113 is driven, and the direction of drive depends on whether the worm-wheel 120 is threaded right or left hand. A change in the speed of the camshaft 6l correspondingly changes the speed of the thread-guides in their back-and-forth motions. If a iine thread is being wound, the differential gear 113 should be made to move comparatively slow, whereas if a coarse thread is being wound the differential gear should be made to move comparatively fast to avoid the thread-spirals piling upon each other. The Variation in speed of the cam shaft also varies the distance apart of the spirals of thread during the winding operation. If the speed of the differential gear is comparatively fast, the spirals of thread will be comparatively wide apart, whereas if the speed of the differential gear is comparatively slow the spirals of thread will be comparatively close together. According to the character or size of the cord or thread, the speed of the differential gear 113 requires to be comparatively fast or slow. If a fine thread is to be Wound, the differential gear must be slowly rotated, which is effected by mounting a comparatively large worm gear or Wheel on the worm gear or wheel shaft 118; but if a coarse thread is to be wound the differential gear must be rotated faster, and this is effected by mounting a smaller worm gear or wheel on the worm gear or wheel shaft. The rotation of the drive-shaft 26 imparts motion to the differential or epicycle train through the medium of the gear-wheels 106 and 107, while the Aworm 120 imparts motion to the worm-wheel,

and this motion, which can he varied by the interchangeable worm-gears, is transmitted to the differential gear 113 through the medium of the bevel-gears 117 and 115 and the pinion 114. The principle of operation of the gears 108, 109, 110, 111, and 113 is like or similar to that of the gearing of the wellknown equational box.

In Fig. 11 I show a more simple arrangement for varying the speed of the cam-shaft, comprising two cone-pulleys 124: and 125, one, 124, being fast on the drive-shaft 26 and the other, 125, being fast on the camshaft 61. Said pulleys are geared together by means of a belt 126, which may be moved to one side or the other by means of a shifter 127, sliding on a rod 128. The shifter may be held in any adjusted position on the rod 128 through the medium of the set-screw 129. The rod 128 is rigidly fastened in a support 130, mounted on the frame of the machine.

IOC

IIO

The central diameter of cone-pulley 124 is exactlygone-half that of cone-pulley 125. When the belt 126 is exactly in the center of the pulleys, the drive-shaft 26 will make two revolutions to one of the cam-shaft. Drivegear is three times the size of bevel-gear 24, and the bevel-gear 18 on shaft 16 and the bevel-gear 8 on spindle 1 are the same size. Hence the spindle 1 makes six revolutions to one of the cam 48 when the belt is in the center of the pulleys. This central position of the belt would cause the thread to travel around the spindle in spirals that would lie one over the other; but shifting the belt 126 to one side or the other of the center will slightly vary the relative speeds of the spindle and cam, so

- that the spirals will lie one beside the other,

either close together or wide apart, according to the distance the belt is shifted from the central position. The cam 48 gives two complete traverses to the thread-guide-one forward and one backward-in each of its revolutions. The spindle 1 will therefore in the arrangement described turn three times to each traverse or complete movement in one direction of the threadguide, thereby causing the thread to warp or wind three times around the cop-tube in a spiral formation in each of such movements. This is what is known in the art as a three-wind. In like manner by using a larger drive-gear 25 ora lsmaller driven gear 24, so that the former shall be four times the size of the latter, a fourwind could be produced, or by making the gear 25 only twice the size of the gear 24 a two-Wind could be produced. The change of worm-gear 119 to regulate the lay of the thread and the increase or decrease of this change-gear in size has the same effect as shifting the belt 126 a little distance or longer distance from the central position. When the gear 119 is not in use-that is, when the worm-gear shaft 118 is stationary, the threads will wind, just as when the belt 126 lies centrally of the pulleys-that is, they will pile one on top of the other. When the gear 119 is used, it has the same effect as shifting the belt 126 to one side or the other. The use of a right hand threaded worm 120 corresponds with shifting the belt 126 one way, and the use of a left-hand worm corresponds with shifting the belt 126 the other way.

Any suitable form of tension device 131 may be employed for imparting the requisite tension to the thread being wou nd on the coptube. l

Having thus fully described-my invention, what I claim as new is 1. In a thread-winding machine, in combivnation with the frame of the machine, a spindle-frame mounted thereon having an aperture, a driven shaft extending through said aperture and having a bevel-gear, a windingspindle mounted in the spindle-frame and having a bevel-gear in mesh with said shaftgear, a thread-guide carrier mounted to slide in a rectilinear path toward and from said spindle, a thread-guide mounted in said carrier, means for reciprocating said threadguide, said spindle-frame being adapted to be turned upon said shaft as a center to vary the position of the spindle relative to the thread-guide carrier, and means for holding said spindle-frame in its adjusted position.

2. In a thread-winding machine, in combination with the winding-spindle, a threadguide carrier mounted to slide in a rectilinear path toward and from said spindle, a threadguide mounted in said carrier, a cam-shaft, a cam thereon for reciprocating said threadguide, and means for causing said cam to slide back and forth on its shaft in unison with said thread-guide carrier.

3.
